We report novel rocking long period gratings (R-LPGs) made by introducing permanent periodic twist along a standard single mode fiber. Very high coupling efficiency of 32.5 dB was achieved with 23 periods and a 2° rocking angle. The responses of R-LPGs to temperature, strain, and torsion were tested. Compared with a normal LPG written under the same conditions, the R-LPGs were found to have a similar sensitivity to temperature, five times smaller sensitivity to strain, and insensitive to twist.
